Mishkat al-Masabih 3554
وَعَن أبي غالبٍ رأى أَبُو أُمامةَ رؤوساً مَنْصُوبَةً عَلَى دَرَجِ دِمَشْقَ فَقَالَ أَبُو أُمَامَةَ: «كِلَابُ النَّارِ شَرُّ قَتْلَى تَحْتَ أَدِيمِ السَّمَاءِ خَيْرُ قَتْلَى مَنْ قَتَلُوهُ» ثُمَّ قَرَأَ (يَوْمَ تبيَضُّ وُجوهٌ وتَسوَدُّ وُجوهٌ) الْآيَةَ قِيلَ لِأَبِي أُمَامَةَ: أَنْتَ سَمِعْتُ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ؟ قَالَ: لَوْ لَمْ أَسْمَعْهُ إِلَّا مَرَّةً أَوْ مَرَّتَيْنِ أوْ ثَلَاثًا حَتَّى عَدَّ سَبْعًا مَا حَدَّثْتُكُمُوهُ. رَوَاهُ التِّرْمِذِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ حَسَنٌ
Abu Ghalib reported: Abu Umama saw heads displayed on the steps of Damascus and said: The dogs of Hell are the worst of those killed beneath the sky; the best of those killed are the ones who kill them. Then he recited the verse, On the day when some faces will be bright and some faces will be dark, through the end of the verse. Abu Umama was asked, Did you hear this from the Messenger of God? He said, If I had heard it from him only once, or twice, or three times—he counted up to seven—I would not have related it to you. Al-Tirmidhi and Ibn Majah transmitted it. Al-Tirmidhi said: This is a fair hadith.
Translation notes
The Arabic says Abu Umama counted up to seven; the translation retains that detail without expanding the quoted Quranic verse.
